ABSTRACT:
A fuel injection nozzle has a tubular body adapted to receive fuel from a fuel line. A restriction member received at the inlet end of the tubular member limits the flow of fuel into the nozzle and is adjustable between minimum and maximum flow rates. The restriction member has an upstream member with a maximum flow orifice through which fuel entering the nozzle passes. A downstream restriction member nests within the upstream member such that a wall of the downstream member is in circumjacent, sliding relationship to a corresponding wall in the upstream member. The downstream member has a minimum flow orifice for establishing the minimum fuel flow into the nozzle and orifices in the wall portion which are blocked by the wall portion of the upstream member in the minimum flow position of the members and are subject to progressive unblocking to thereby establish a flow rate through the nozzle above the minimum.
